The quantity calculation and proportional delivery-tax allocation behavior in src/pricing.rs, context/tier/quantity selection behavior in src/context.rs, and numeric epsilon/null comparison semantics in src/rule_comparison.rs, are partial behavioral port of Shopware Core 6.7.14.2, reference commit de074a584d77d8abb09ddb21d8799f083a61a3da.

reference/price.php, reference/context.php, reference/delivery.php, and reference/rules.php instantiate the original installed upstream classes; the repository does not vendor Shopware, a commercial B2B package, or a model. PHP rounding behavior was checked against the official PHP 8.5 runtime and https://github.com/php/php-src/blob/PHP-8.5/ext/standard/math.c . No PHP C source is bundled. The reference assumes default PHP precision=14 and the PHP 8.4+ decimal rounding behavior. Other runtime settings require a new gate.

All catalog products, accounts and vector illustrations are synthetic demo content authored for this prototype. No merchant/customer data is included. Rust/npm dependencies retain their respective licenses. Model weights and their licenses must be obtained separately through the chosen model provider.

Database and search stack

• PostgreSQL: PostgreSQL License, https://www.postgresql.org/about/licence/
• Apache AGE: Apache License 2.0, https://github.com/apache/age/blob/PG17/LICENSE
• pgvector: PostgreSQL License, https://github.com/pgvector/pgvector/blob/v0.8.6/LICENSE

Fresh installations use standard PostgreSQL and Qdrant v1.16.3 (Apache 2.0, https://github.com/qdrant/qdrant/blob/v1.16.3/LICENSE). AGE and pgvector are legacy dependencies retained for migration. The legacy database/Dockerfile builds AGE at commit 502f2c1fa32a04497dc286237186e58ac4956a53 and pgvector at tag v0.8.6. No BSL/SSPL database or proprietary edition is required. Model-provider APIs remain optional external services.

Document parser

pdf-extract 0.12.1 (MIT) extracts searchable PDF text. libc (MIT OR Apache-2.0) provides CPU limits and Linux address-space limits for its child process. Dependencies remain external registry packages and retain their bundled license files. No OCR, parser microVM, or arbitrary customer-code execution is implied.

Bundled geography

fixtures/geography.json derives country codes/continents and localized names from countries-list 3.4.1 and i18n-iso-countries 7.14.0 (MIT). Their copyright and license notices are preserved in countries-list.txt and i18n-iso-countries.txt. US subdivision codes use the US Census state reference. Dataset versions, the explicit non-ISO XK entry and limits are documented in international-commerce.md.
